Virtual Wind Tunnel: Rear Wing Drag and Down Forces

The table below show the drag and down force results for the CFD "virtual wind tunnel" simulation of the rear wing of a Kyosho Mini-Z MR03 Mazda 787b model:

Speed (m/s)

Note that these numbers are only for the rear wing, and not for the full body. That is, these are the forces resulting from the air flowing through the rear wing. In a way, they represent the impact of the rear wing on the overall car aerodynamics.
